When the water level drops below your set point, the float valve opens to\n    add water until the proper level is restored. If the level rises too high, the built-in overflow helps remove excess water to reduce\n    overfilling and water waste.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eKey Features\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAutomatic water level control:\u003c\/strong\u003e Helps keep water at a steady operating level for reliable skimming and circulation.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSide-mounted float valve:\u003c\/strong\u003e Mechanical float design meters in water as needed without electronics.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBuilt-in overflow:\u003c\/strong\u003e Helps protect against overfilling and related water waste.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompact housing:\u003c\/strong\u003e Approximately 7\" diameter deck canister fits many new builds and renovations.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDurable construction:\u003c\/strong\u003e Corrosion- and chemical-resistant ABS polymer body designed for outdoor pool environments.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Gray lid\/ring (T40BG).\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eCommon Applications\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eIn-ground pools and spas where maintaining a consistent water level protects equipment and improves day-to-day operation\u003c\/li\u003e\n    \u003cli\u003eNew construction and remodels requiring a compact in-deck autofill canister\u003c\/li\u003e\n    \u003cli\u003eInstallations where a non-electronic, mechanical water leveler is preferred\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eHow It Works\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eAs the pool water level drops, the float lowers and opens the fill valve to add make-up water.\u003c\/li\u003e\n    \u003cli\u003eOnce the set level is reached, the float rises and closes the valve to stop filling.\u003c\/li\u003e\n    \u003cli\u003eIf water rises above the normal level, the overflow pathway helps carry away excess water.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eWhen to Replace\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eWater level no longer holds steady (valve won’t open\/close consistently)\u003c\/li\u003e\n    \u003cli\u003eContinuous filling or frequent overfilling\u003c\/li\u003e\n    \u003cli\u003eCracked canister, damaged lid, or worn internal float\/valve components\u003c\/li\u003e\n    \u003cli\u003eSticking float or debris-related valve issues that return soon after cleaning\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eConfirm your desired set waterline height and orient the side-mounted float so it moves freely without contacting the canister walls.\u003c\/li\u003e\n    \u003cli\u003eUse a proper backflow prevention method per local code on the water supply line to the autofill.\u003c\/li\u003e\n    \u003cli\u003eAfter installation, test fill shutoff and overflow operation before leaving the system unattended.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eMaintenance Tip\u003c\/h3\u003e\n  \u003cp\u003e\n    Periodically remove the lid and check for debris, scale, or insects that can restrict float movement.
